Embodiment Construction

[0016] The present invention will be described in detail below with reference to the accompanying drawings.

[0017] As shown in the figure, the present invention includes a microprocessor control board, an iron concentration sensor and a solenoid coil. The microprocessor control board uses a single-chip microcomputer as the core to design a peripheral circuit, mainly including a thyristor pulse trigger circuit, an iron concentration Oscillating circuit, sensor, control keyboard and display circuit are composed. Use circuit drawing software to design the schematic diagram, and then make it into a printed circuit board (PCB). Install each chip, pulse transformer, etc. on the PCB; the power capacitor is charged in 3 hours and discharged to the magnetic field coil in a hour.

[0018] For the iron concentration sensor, a coil is wound on a round pipe with a flange to form an iron concentration sensor with an inductance value of 0.96mH and connected to the microprocessor control b...

Abstract

A pulse vibration pre-magnetizer relates a ferrous powder magnetization treatment device, which comprises a microprocessor control panel, an iron concentration sensor and a solenoid, wherein the microprocessor control panel taking a single chip computer as a core is provided with a peripheral circuit which is made into a printed circuit board, and chips and a pulse transformer are mounted on the printed circuit board. The iron concentration sensor is connected with the microprocessor control panel; two individual solenoids are uniformly wound from copper wires on ore pulp piplines. The ferrous powder magnetization treatment device enables magnetic substances to remain sufficiently residual magnetism via processing by the pre-magnetizer for agglomerating the residual magnetism and preparing for increasing recovery ratio. The invention is the development pulse pre-magnetizer capable of generating high field strength and can operate continuously.

Description

technical field [0001] The invention relates to iron powder magnetization treatment equipment, in particular to a pulse vibration premagnet used for magnetization treatment of magnetic medium and magnetite in dense medium coal preparation. Background technique [0002] Before the magnetic iron ore powder slurry in the iron ore dressing plant enters the desliming tank, the magnetic field strength of the desliming tank is small, so it is necessary to remove the magnetic iron powder in the iron ore powder slurry before the iron ore powder slurry enters the desliming tank. Pre-magnetization treatment makes it agglomerate; the dense medium of dense medium coal preparation generally uses fine-grained magnetic iron ore powder, which forms a dilute medium slurry in the process flow, and the fine-grained magnetic iron ore in the dilute medium slurry The powder is recovered by magnetic separation after concentrated treatment. In order to accelerate the concentration speed and recovery...
